I have an nearly minimal config for Solr 4.9, 5.5 and 6.2 at: https://github.com/arafalov/simplest-solr-config/ . They are _quite_ feature minimal (6.2 does not even have ID or version), but they will import and search example/exampledocs/*.xml without fuss
I challenge you to guess number of lines they take before looking :-) As to minimal examples, I think that's absolutely the next step. Did you ever notice that we don't even get too many question on the Solr Users mailing list about the example - I suspect it is because people get lost so fast they don't even know how to ask the questions. SOLR-9601 will be my next experiment for that. As to kitchen-sync vs the examples, maybe we need a "configuration" configset that will have all the definitions and then have Admin/Velocity/whatever UI that allows user pick a definition and existing core on the same server and it will the type/field/configuration command to that core. It is definitely doable for schema. For solrconfig it is a bit more challenging as not everything is API controlled yet and API itself - in my mind - is still very raw. The support files is a small challenge too for non-cloud mode. But this could be the dogfood project to fix that. So, as a workflow, it would be: 1) bin/solr create -c mycore -d minimal_config 2) Experiment to the limit of that core's configuration (initial types, etc) 3) bin/solr create -c config -d configuration 4) Use the new core's enhanced UI to do whatever is needed to mycore 5) bin/solr delete -c config 6) Continue working with mycore The other similar idea is a 3rd party solr config wizard that walks the user through the choices and generates config files with/without comments/links to ref guide. Then, it is not limited to Solr file layout. On the other hand, people need to know the tool exists.... Regards, Alex. P.s. I will try very hard to be at the meetup on Tuesday, so will be very happy to have an in-depth discussion about this topic ---- Newsletter and resources for Solr beginners and intermediates: http://www.solr-start.com/ On 5 October 2016 at 21:15, Erick Erickson <erickerick...@gmail.com> wrote: > Charlie: > > I like that idea.
